HELVETICA CHIMICA ACTA - Vol. 61, Fasc. 3 (1978) Nr. 117 1207 ... 117. PrCparation de quelques 4-nitroisoxazoles a partir de pseudonitrosites de cCtones Cthyleniques du type chalcone ... The Synthesis of some 4-Nitroisoxazoles from Pseudonitrosites of Chalcones ... Summary The action of dinitrogen trioxide with a, /3-unsaturated ketones of the chalcone type leads to pseudonitrosites (Table 1) which are cyclized to 4-nitro-3,5-diarylisoxa- zoles (Table 2).
